步骤：
1、VScode中安装Eslint和live Server（本地服务器）插件；
2、按照以下package.json安装相应的开发包：
{

// "rootDirs": [], /* List of root folders whose combined content represents the structure of the project at runtime. */
// "typeRoots": [], /* List of folders to include type definitions from. */

},
"include": [
"src/**/*"
],
"exclude": [
"node_modules"
]
}
4、配置.eslintrc.json：
{
"parser": "@typescript-eslint/parser",
"plugins": [
"@typescript-eslint",
"html"
],
"parserOptions": {
"ecmaVersion": 6,
"sourceType": "module"
},
"extends": [
"eslint:recommended",
"plugin:@typescript-eslint/eslint-recommended",
"plugin:@typescript-eslint/recommended"
],
"env": {
"node": true,
"browser": true,
"commonjs": true,
"es6": true,
"jquery": true
},
"rules": {
"no-alert": 0 //禁止使用alert confirm prompt
}
}5、安装VScode插件Easy LESS；
6、VScode的配置文件setting.json中添加如下代码使得在文件保存时ESlint自动检查代码格式：
"files.autoSave": "off",
"eslint.autoFixOnSave": true,
"eslint.run": "onSave",
"eslint.validate": [
"javascript",
"html",
{
"language": "jsx",
"autoFix": true
},
{
"language": "html",
"autoFix": true
},
{
"language": "typescript",
"autoFix": true
}
]6、VScode的配置文件setting.json中添加如下代码使得在编辑Less文件保存时，自动生成相应的Css：
"less.compile": {
"compress": false,
"sourceMap": false,
"out": "${workspaceRoot}\dist\static\css\", // 这里是代表编译后生成的css文件所放的位置
},编辑后的setting.json文件为：
{
"files.autoSave": "off",
"eslint.autoFixOnSave": true,
"eslint.run": "onSave",
"eslint.validate": [
"javascript",
"html",
{
"language": "jsx",
"autoFix": true
},
{
"language": "html",
"autoFix": true
},
{
"language": "typescript",
"autoFix": true
}
],
"terminal.integrated.rendererType": "dom",
"less.compile": {
"compress": false,
"sourceMap": false,
"out": "${workspaceRoot}\dist\static\css\", // 这里是代表编译后生成的css文件所放的位置
},
"liveServer.settings.donotVerifyTags": true
}
